[Transcortin in rat kidney tissue: distribution in microsomal fractions]. 1991

K I Krauialis, and A P Ulinskaĭte, and V I Meĭlus

During chromatography of renal tissue cytosolic proteins on DEAE-cellulose the protein specifically binding [3H]corticosterone is eluted within the potassium phosphate concentration range of 0.08-0.10 M. Analysis of kidney slices revealed the synthesis of [3H]transcortin whose electrophoretic mobility was close to that of the blood plasma protein. Using radioimmunochemical methods, it has been found that transcortin-specific [125I]IgG antibodies interact with growing polypeptide chains of membrane-bound polyribosomes. Free polyribosomes do not bind antibodies against transcortin.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D008297	Male		Males
D008861	Microsomes	Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)	Microsome
D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.	Radioimmunoassays
D002848	Chromatography, DEAE-Cellulose	A type of ion exchange chromatography using diethylaminoethyl cellulose (DEAE-CELLULOSE) as a positively charged resin. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)	DEAE-Cellulose Chromatography,Chromatography, DEAE Cellulose,DEAE Cellulose Chromatography
D003345	Corticosterone	An adrenocortical steroid that has modest but significant activities as a mineralocorticoid and a glucocorticoid. (From Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1437)
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000906	Antibodies	Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
D014156	Transcortin	A serpin family member that binds to and transports GLUCOCORTICOIDS in the BLOOD.	Corticosteroid-Binding Globulin,Serpin A6,Corticosteroid Binding Globulin
